## Pricing

from $4.40 / 1,000 results

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## Dam Safety Risk Monitor — USACE National Inventory of Dams (NID)

Search and monitor **92,000+ US dams** from the US Army Corps of Engineers **National Inventory of Dams** and get a normalized, analysis-ready record per dam with a **composite risk score** built from three signals regulators track: **hazard potential**, **latest condition assessment**, and **inspection staleness** — plus flags for dams with **no Emergency Action Plan (EAP)** on file.

No API key, no scraping fragile HTML: data comes straight from the official USACE NID ArcGIS service.

### Who this is for

- **P&C insurers and reinsurers** — underwrite flood and property exposure downstream of high-hazard dams; screen a book of locations against poor-condition, overdue-inspection dams.
- **Dam-safety and civil engineers** — build state watchlists of High-hazard dams in Poor/Unsatisfactory condition or with stale inspections.
- **Infrastructure due-diligence and real-estate risk teams** — check dams near an asset, portfolio, or development site before acquisition.
- **Journalists, researchers, and emergency managers** — track dams missing Emergency Action Plans, county by county.

### What it does

1. Queries the USACE NID FeatureServer (keyless, official) with your state / hazard / condition / owner filters.
2. Normalizes each dam into a clean snake_case record (trimmed names, ISO dates, parsed county).
3. Computes `risk_score` = hazard weight (High 10 / Significant 5 / Low 1) × condition weight (Unsatisfactory 3.5 / Poor 3 / Fair 2 / Satisfactory 1) × inspection-staleness factor (1.0 fresh → 3.0 at 20+ years), + 5 when no current EAP. Range ≈ 1–110.
4. Adds machine-readable `risk_flags` such as `high_hazard_poor_condition`, `inspection_stale_10yr`, `eap_missing`.
5. Optional client-side screens: `minRiskScore` and `requireMissingEap`.

### Example input

```json
{
  "states": ["CO"],
  "hazardPotential": ["High"],
  "conditionAssessment": ["Poor", "Unsatisfactory"],
  "minRiskScore": 40,
  "requireMissingEap": false,
  "maxResults": 500
}
````

States accept postal codes (`CO`) or full names (`Colorado`). Leave `states` empty to scan the whole country (bounded by `maxResults`).

### Output fields (one record per dam)

`nid_id`, `federal_id`, `name`, `state`, `county`, `city`, `river`, `latitude`, `longitude`, `owner_type`, `primary_purpose`, `primary_dam_type`, `dam_height_ft`, `max_storage_acre_ft`, `year_completed`, `hazard_potential`, `condition_assessment`, `condition_assess_date`, `last_inspection_date`, `inspection_age_years`, `inspection_frequency_years`, `eap_status`, `eap_last_rev_date`, `operational_status`, `risk_score`, `risk_flags[]`, `data_updated`, `source_url`

### Use as an MCP tool

This actor works as a clean, chainable **MCP tool** for AI agents (Claude, Cursor, etc.) via `mcp.apify.com` — the input and every output field are fully described, so an agent can query "high-hazard poor-condition dams in Texas without an EAP" unassisted.

### Monitoring

Schedule it (e.g. weekly per state) and diff `risk_score`, `condition_assessment`, and `eap_status` between runs to catch downgraded dams the day the inventory updates.

### FAQ

**How many high hazard dams are in my state?** Run with `states=["<your state>"]`, `hazardPotential=["High"]` — the dataset count is the answer, each row a dam.

**Which dams near me are in poor condition?** Filter your state with `conditionAssessment=["Poor","Unsatisfactory"]`, then sort by `risk_score` or filter by county.

**Which dams have no emergency action plan?** Set `requireMissingEap: true`. High-hazard dams without an EAP are the classic regulatory red flag.

**Is the National Inventory of Dams free / do I need an API key?** Yes, free and keyless — this actor reads the official USACE public ArcGIS service directly.

**How is the dam risk score calculated?** Hazard × condition × years-since-inspection, plus an EAP penalty — see "What it does" above; `risk_flags` explains every contributing factor per dam.

**How current is the data?** The NID is updated continuously by USACE and state regulators; each record carries its `data_updated` date.

# Actor input Schema

## `states` (type: `array`):

US states to search, as 2-letter postal codes (CO, TX) or full names (Colorado). Leave empty to search the whole national inventory (bounded by Max results). Note: the NID API stores full state names; codes are converted automatically.

## `hazardPotential` (type: `array`):

Filter by downstream hazard potential classification. Valid values: High, Significant, Low, Undetermined. Leave empty for all hazard classes.

## `conditionAssessment` (type: `array`):

Filter by latest condition assessment. Valid values: Unsatisfactory, Poor, Fair, Satisfactory, Not Available. Leave empty for all conditions.

## `ownerType` (type: `array`):

Filter by primary owner type. Valid values: Federal, State, Local Government, Public Utility, Private, Not Listed. Leave empty for all owners.

## `minRiskScore` (type: `integer`):

Only output dams whose composite risk\_score is at least this value (scale roughly 1 = low-hazard/satisfactory/freshly inspected to 110 = high-hazard/unsatisfactory/20+ years uninspected/no EAP). Leave empty to output all matching dams.

## `requireMissingEap` (type: `boolean`):

If true, only output dams that do NOT have an Emergency Action Plan on record (EAP missing, not required, or not available).

## `maxResults` (type: `integer`):

Maximum number of dam records to output (each record is one billed result). The full inventory is ~92,000 structures, so keep this bounded.

## Actor input object example

  "states": [
    "CO"

  "hazardPotential": [
